Abstract
A light source including a plurality of light emitting areas formed in a two-dimension array is mounted on a substrate. A holding member holds an optical system that shapes a laser beam emitted from each of the light emitting areas, a splitting element that splits a part of the laser beam passed through the optical system, and a light receiving system that receives split laser beam. A base member including an aligning unit that aligns the light source in a direction along an optical axis of the optical system and a direction perpendicular to the optical axis is connected to the holding member. An elastic member presses the substrate against the base member.
